Who conquered the Aztec empire and his troops?

The Aztec Empire was conquered by Spanish conquistador Hernán Cortés and his troops in 1521. Cortés leveraged alliances with indigenous tribes discontented with Aztec rule, alongside superior weaponry and tactics, to defeat the Aztecs. The fall of their capital, Tenochtitlán, marked the end of the empire and the beginning of Spanish colonization in Mexico.
